956 an existing .py counterpart, override the co_filename attributes of all

Vinay Sajip6badbe92009-01-20 22:49:13 +0000996- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000997 method on file objects with closefd=False. The file descriptor is still

1372What's New in Python 2.6.1
1373==========================
1374
1375*Release date: 04-Dec-2008*
1376
1377Core and Builtins
1378-----------------
1379
1380- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1381 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1382 instead of throwing a MemoryError.
1383
1384- Issue #4367: Python would segfault during compiling when the unicodedata
1385 module couldn't be imported and \N escapes were present.
1386
1387- Issue #4348: Some bytearray methods returned that didn't cause any change to
1388 the bytearray, returned the same bytearray instead of a copy.
1389
1390- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1391
1392- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1393
1394- Issue #4048: The parser module now correctly validates relative imports.
1395
1396- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1402- Issue #4209: Enabling unicode_literals and the print_function in the same
1403 __future__ import didn't work.
1404
1405- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1406 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1407 really executed because I cannot move to such directory on win2k)
1408
1409- Issue #4069: When set.remove(element) is used with a set element, the element
1410 is temporarily replaced with an equivalent frozenset. But the eventual
1411 KeyError would always report the empty frozenset([]) as the missing key. Now
1412 it correctly refers to the initial element.
1413
1414- Fixed C99 style comments in several files. Python is now C89 compatible
1415 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001564- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1565 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1566 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1567 ``printf`` function, whereas PyString_FromFormat has an independent

Vinay Sajip35e3b032008-09-01 14:33:59 +00001589- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001590 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1591 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1592 when given a tuple of classes as second argument, were looking up
1593 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1594 type object.
1595
Neal Norwitz18aa3882008-08-24 05:04:52 +00001596- Fix crashes on memory allocation failure found with failmalloc.

1665 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1666 for catch_warnings() also led to an improvement in the raising of a
1667 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001689- Issue #2975: When compiling several extension modules with Visual Studio 2008
1690 from the same python interpreter, some environment variables would grow
1691 without limit.
1692
Benjamin Peterson37346b22008-08-23 20:27:43 +00001693- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001730What's New in Python 2.6 beta 3?
1731================================
1732
Barry Warsaw07a4a382008-08-21 01:15:08 +00001733*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001734
1735Core and Builtins
1736-----------------
1737
Guido van Rossumf8402962008-08-20 15:01:50 +00001738- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1739 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1740 extensions do not automatically benefit from the class attribute
1741 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1742 to their tp_flags field if they care. This is a backwards
1743 compatibility feature; in 3.0, all types will use the cache by
1744 default.
1745
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001746- Keyword arguments can now follow starred arguments. (``f(a, *args,
1747 keyword=23)`` is now valid syntax.)
1748
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001749- ctypes function pointers that are COM methods have a boolean True
1750 value again.
1751
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001752- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1753 by denying s# to parse objects that have a releasebuffer procedure,
1754 and introducing s*.
1755
Georg Brandl1e13ea92008-08-11 09:07:59 +00001756- Issue #3537: Fix an assertion failure when an empty but presized dict
1757 object was stored in the freelist.
1758
Mark Dickinsonb6467572008-08-04 21:30:09 +00001759- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1760 ValueError consistently across platforms.
1761
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001762- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1763 (64bit Unix, for example), unichr() would truncate its argument and return
1764 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1765
Neal Norwitze7d8be82008-07-31 17:17:14 +00001766- Apply security patches from Apple.
1767
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001768- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1769 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1770
Antoine Pitrou92f82162008-07-25 22:22:08 +00001771- Issue #1819: function calls with several named parameters are now on
1772 average 35% faster (as measured by pybench).
1773
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001774- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1775 the python debugger steps into a class statement: the free variables (local
1776 variables defined in an outer scope) would be deleted from the outer scope.
1777
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001778- Issue #2620: Overflow checking when allocating or reallocating memory
1779 was not always being done properly in some python types and extension
1780 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1781 all been updated to perform better checks and places in the code that
1782 would previously leak memory on the error path when such an allocation
1783 failed have been fixed.

1786-------
1787
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001788- Issue #3612: Added some missing basic types in ctypes.wintypes.
1789
Benjamin Petersone977ad42008-08-20 01:42:01 +00001790- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1791 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1792
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001793- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1794 version reported by these tools does not necessarily follow the python
1795 version numbering scheme, so the module is less strict when parsing it.
1796
Nick Coghlanf70385a2008-08-18 12:42:46 +00001797- Issue #2235: Added Py3k warnings for types which will become unhashable
1798 under the stricter __hash__ inheritance rules in 3.0. Several types
1799 which did not meet the rules for hash invariants and were already
1800 unhashable in 3.0 have now been explicitly flagged as unhashable in
1801 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1802 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1803
Brett Cannon88f801d2008-08-18 00:46:22 +00001804- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1805 imported into the module but exposed as part of the module's API.
1806
Brett Cannon7b96f072008-08-18 00:41:11 +00001807- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1808
Brett Cannon46225e72008-08-18 00:36:52 +00001809- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1810
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001811- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1812
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001813- Issue #3575: Incremental decoder's decode function now takes bytearray
1814 by using 's*' instead of 't#'.
1815
Jesus Cea585ad8a2009-07-02 15:37:21 +00001816- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001817 fails unicode conversion on 2nd parameter. (windows only)
1818
Facundo Batista94f243a2008-08-17 03:38:39 +00001819- Issue 2464. urllib2 now supports a malformation in the URL received
1820 in a redirect.
1821
Brett Cannonabe423e2008-08-16 21:47:07 +00001822- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001823 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001824
Facundo Batistaeb90b782008-08-16 14:44:07 +00001825- Issue #2776: fixed small issue when handling an URL with double slash
1826 after a 302 response in the case of not going through a proxy.
1827
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001828- Issue #2676: in the email package, content-type parsing was hanging on
1829 pathological input because of quadratic or exponential behaviour of a
1830 regular expression.
1831
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001832- Issue #3476: binary buffered reading through the new "io" library is now
1833 thread-safe.
1834
Brett Cannonbf3157b2008-08-14 05:00:03 +00001835- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1836 since mimetools itself is deprecated. Because modules are cached, all
1837 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1838
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001839- Issue #3134: shutil referenced undefined WindowsError symbol.
1840
Robert Schuppenies14646332008-08-10 11:01:53 +00001841- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1842 menu entries were not deleted.
1843
Brett Cannon83e81842008-08-09 23:30:55 +00001844- Copied the implementation of reduce() to _functools.reduce() to have a
1845 version that did not raise a DeprecationWarning under -3.
1846
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001847- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1848 a MemoryError rather than silently stop the iteration.
1849
Guido van Rossum59ce9012008-08-09 14:55:34 +00001850- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1851 to _sre.compile() will now be rejected. This should not affect anybody
1852 since the re.compile() function never generates invalid re-bytecode.
1853
Skip Montanaroa032bf42008-08-08 22:52:51 +00001854- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1855 upon first access it can be automatically initialized from the csv file if
1856 it wasn't initialized during instantiation.
1857
Brett Cannon3aa2a492008-08-06 22:28:09 +00001858- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1859 the reload() built-in has been removed.
1860
Brett Cannon7e30b672008-08-04 21:52:25 +00001861- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001862 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1865 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1866 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1867 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001868
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001869- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1870 raised an AttributeError.
1871
Benjamin Peterson01a24322008-07-28 23:35:27 +00001872- Issue #2523: Fix quadratic behaviour when read()ing a binary file without

1930-----------------
1931
Georg Brandl3e483f62008-07-16 22:57:41 +00001932- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1933 its methods now allow for items objects that can be converted to
1934 an integer using operator.index().
1935
Mark Dickinson64b7e502008-07-16 09:40:03 +00001936- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1937 produced a ValueError instead of giving the correct float.
1938
Eric Smitha5fa5a22008-07-16 00:11:49 +00001939- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1940 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1941
Mark Dickinson7103aa42008-07-15 19:08:33 +00001942- Issue #3008: the float type has a new instance method 'float.hex'
1943 and a new class method 'float.fromhex' to convert floating-point
1944 numbers to and from hexadecimal strings, respectively.
1945
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001946- Issue #2235: __hash__ is once again inherited by default. To allow
1947 collections.Hashable to remain meaningful in the presence of the
1948 default hash implementation (object.__hash__), it is now possible
1949 to explicit block inheritance of hash by setting __hash__=None at
1950 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1951 level.
1952
Nick Coghlanb028f502008-07-13 14:52:36 +00001953- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1954 the parent module cannot be found while performing an absolute import.
1955 This means that an incorrectly defined __package__ attribute will
1956 now only prevent relative imports in that module rather than causing
1957 all imports from that module to fail.
1958
Nick Coghlan14ff9942008-07-08 14:21:42 +00001959- Issue #2517: Allow unicode messages in Exceptions again by correctly

1969 another thread's dictionary.
1970
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001971- Issue #3004: Minor change to slice.indices(): the start and stop
1972 arguments are now treated identically, making the behaviour easier
1973 to describe and understand. For example, slice(None, -10,
1974 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1975 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1976 10, -1).
1977
Georg Brandl278fc502008-07-19 12:46:12 +00001978- Issue #3219: Calling a function with repeated keyword arguments,
1979 f(a=2, a=23), would not cause a syntax error. This was a regression
1980 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002018- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2019 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002020 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002021 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002037- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Issue #1631171: Re-implement the 'warnings' module in C (the
2493 original Python code has been kept as backup). This will allow for
2494 using the 'warning's machinery in such places as the parser where
2495 use of pure Python code is not possible. Both the ``showarning()``
2496 and ``formatwarning()`` gain an optional 'line' argument which is
2497 not called by default for backwards-compatibility reasons. Setting
2498 ``warnings.showwarning()`` to an implementation that lacks support
2499 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002541- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002542 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002562- Issue #2550: The approach used by client/server code for obtaining
2563 ports to listen on in network-oriented tests has been refined in an
2564 effort to facilitate running multiple instances of the entire
2565 regression test suite in parallel without issue.
2566 test_support.bind_port() has been fixed such that it will always
2567 return a unique port -- which wasn't always the case with the
2568 previous implementation, especially if socket options had been set
2569 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2570 new implementation of bind_port() will actually raise an exception
2571 if it is passed an AF_INET/SOCK_STREAM socket with either the
2572 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2573 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2574 the socket it's been passed. This currently only applies to
2575 Windows. This option prevents any other sockets from binding to the
2576 host/port we've bound to, thus removing the possibility of the
2577 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2578 when a second SOCK_STREAM socket binds and accepts to a host/port
2579 that's already been bound by another socket. The optional preferred
2580 port parameter to bind_port() has been removed. Under no
2581 circumstances should tests be hard coding ports!
2582
2583 test_support.find_unused_port() has also been introduced, which will
2584 pass a temporary socket object to bind_port() in order to obtain an
2585 unused port. The temporary socket object is then closed and
2586 deleted, and the port is returned. This method should only be used
2587 for obtaining an unused port in order to pass to an external program
2588 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2589 a parameter to a server-oriented class that doesn't give you direct
2590 access to the underlying socket used.
2591
2592 Finally, test_support.HOST has been introduced, which should be used
2593 for the host argument of any relevant socket calls (i.e. bind and
2594 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002595
2596 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002598 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2599 test_asynchat and test_socket_ssl.
2600
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601 It is now possible for multiple instances of the regression test
2602 suite to run in parallel without issue.

2870
Fred Drakea8ee94b2008-03-01 02:45:07 +00002871- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002872 644. The mode is now inherited from the py file.

2875
2876- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002877
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002878- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002879 issue 215555 for a discussion.
2880
Eric Smitha73fbe72008-02-23 03:09:44 +00002881- Added the future_builtins module, which contains hex() and oct().
2882 These are the PEP 3127 version of these functions, designed to be
2883 compatible with the hex() and oct() builtins from Python 3.0. They
2884 differ slightly in their output formats from the existing, unchanged
2885 Python 2.6 builtins. The expected usage of the future_builtins
2886 module is:
2887 from future_builtins import hex, oct
2888
Eric Smith7ef40bf2008-02-20 23:34:22 +00002889- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2890 exponents for exponents with absolute value < 100. Follows C99
2891 standard. This is a change on Windows, which would use 3 digits.
2892 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2893 so that any alterations it does to the resulting string will be
2894 available in stringlib/formatter.h (for float.__format__).
2895
Eric Smith5a3c1352008-02-19 13:21:56 +00002896- Implemented PEP 3101, Advanced String Formatting. This adds a new
2897 builtin format(); a format() method for str and unicode; a
2898 __format__() method to object, str, unicode, int, long, float, and
2899 datetime; the class string.Formatter; and the C API
2900 PyObject_Format().
2901
Georg Brandl3ee81df2008-05-17 18:14:43 +00002902- Fixed several potential crashes, all caused by specially crafted
2903 __del__ methods exploiting objects in temporarily inconsistent
2904 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002905
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002906- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907 prevent a possible crash: an Abstract Base Class would try to access
2908 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- Clear all free lists during a gc.collect() of the highest generation
2914 in order to allow pymalloc to free more arenas. Python may give back
2915 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Issue #2045: Fix an infinite recursion triggered when printing a
2918 subclass of collections.defaultdict, if its default_factory is set
2919 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002920
Christian Heimesf75dbef2008-02-08 00:11:31 +00002921- Fixed a minor memory leak in dictobject.c. The content of the free
2922 list was not freed on interpreter shutdown.
2923
Georg Brandl5a7eca12010-03-21 19:29:04 +00002924- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002926

2928 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002929 to compact the internal free lists of pre-allocted ints and floats.
2930
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2932 calls. Python expected the return type int but the fork familie
2933 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002934

Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Patch #1473257: generator objects gain a gi_code attribute. This is
2948 the same object as the func_code attribute of the function that
2949 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Issue #1920: "while 0" statements were completely removed by the
2952 compiler, even in the presence of an "else" clause, which is
2953 supposed to be run when the condition is false. Now the compiler
2954 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002955
Guido van Rossumeead05f2008-01-24 18:21:02 +00002956- A few crashers fixed: weakref_in_del.py (issue #1377858);

2962 dynload_win.c. The error is still reported properly.
2963
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002965 several extension methods and modules do not work without unicode
2966 support.
2967
Georg Brandl26543b12008-01-21 18:36:51 +00002968- Issue #1882: when compiling code from a string, encoding cookies in the
2969 second line of code were not always recognized correctly.
2970
Georg Brandl14404b62008-01-19 19:27:05 +00002971- Issue #1679: "0x" was taken as a valid integer literal.
2972
Georg Brandl6caad7d2008-01-26 14:19:22 +00002973- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002974 added.
2975
Christian Heimesc94e2b52008-01-14 04:13:37 +00002976- sys.float_info / PyFloat_GetInfo: The floating point information
2977 object was converted from a dict to a specialized structseq object.
2978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Patch #1816: Added sys.flags structseq. It exposes the status of
2980 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Objects/structseq.c: Implemented new structseq representation. The
2983 patch makes structseqs (e.g. the return value of os.stat) more
2984 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Patch #1700288: added a type attribute cache that caches method
2987 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002988
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002989- Bug #1776: __import__() no longer accepts filenames on any platform.
2990 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002991
Georg Brandlaed6c662008-01-07 17:25:53 +00002992- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2995 envvar and sys.dont_write_bytecode attribute. All these can be set
2996 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Improve some exception messages when Windows fails to load an
2999 extension module. Now we get for example '%1 is not a valid Win32
3000 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3005 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003006
Christian Heimes0a8143f2007-12-18 23:22:54 +00003007- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003008 and INF. float("nan"), float("inf") and float("-inf") now work on
3009 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003010
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Compiler now generates simpler and faster code for dictionary
3012 literals. The oparg for BUILD_MAP now indicates an estimated
3013 dictionary size. There is a new opcode, STORE_MAP, for adding
3014 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Issue #1620: New property decorator syntax was modifying the
3019 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Issue #1538: Avoid copying string in split/rsplit if the split char
3022 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003023
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003024- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003025 SystemError.
3026
Nick Coghlanef01d822007-12-03 12:55:17 +00003027- PEP 366: Allow explicit relative imports when executing modules
3028 inside packages with the -m switch via a new module level
3029 __package__ attribute.
3030
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Issue #1402: Fix a crash on exit, when another thread is still
3032 running, and if the deallocation of its frames somehow calls the
3033 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003034

3039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Issue #1460: The utf-7 incremental decoder did not accept truncated
3041 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Patch #1739468: Directories and zipfiles containing a __main__.py
3044 file can now be directly executed by passing their name to the
3045 interpreter. The directory/zipfile is automatically inserted as the
3046 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Issue #1265: Fix a problem with sys.settrace, if the tracing
3049 function uses a generator expression when at the same time the
3050 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003051
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003052- sets and frozensets now have an isdisjoint() method.
3053
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003054- optimize the performance of builtin.sum().
3055
Neal Norwitz44f326e2007-10-05 05:29:17 +00003056- Fix warnings found by the new version of the Coverity checker.
3057
Georg Brandl5a7eca12010-03-21 19:29:04 +00003058- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3060 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Issue #1686386: Tuple's tp_repr did not take into account the
3063 possibility of having a self-referential tuple, which is possible
3064 from C code. Nor did object's tp_str consider that a type's tp_str
3065 could do something that could lead to an inifinite recursion.
3066 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3067 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Issue #1164: It was possible to trigger deadlock when using the
3070 'print' statement to write to a file since the GIL was not released
3071 as needed. Now PyObject_Print() does the right thing along with
3072 various tp_print implementations of the built-in types and those in
3073 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #1147: Exceptions were directly allowing string exceptions in
3076 their throw() method even though string exceptions no longer
3077 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Issue #1096: Prevent a segfault from getting the repr of a very
3080 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003081
Brett Cannon1e534b52007-09-07 04:18:30 +00003082- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 PyObject_Call() never calling back out to Python code to trigger
3084 recursion depth updates/checks. Required the creation of a static
3085 RuntimeError instance in case normalizing an exception put the
3086 recursion check value past its limit. Fixes crashers
3087 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003088
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Patch #1031213: Decode source line in SyntaxErrors back to its

3093 with %G.
3094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Prevent expandtabs() on string and unicode objects from causing a
3096 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00003101
Neal Norwitz0ac60192007-05-27 04:08:54 +00003102- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103 __*__ attributes. (Some already existed, e.g., __doc__ and
3104 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003105
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003106- Add -3 option to the interpreter to warn about features that are
3107 deprecated and will be changed/removed in Python 3.0.
3108
Georg Brandl2134e752007-05-21 20:34:16 +00003109- Patch #1686487: you can now pass any mapping after '**' in function
3110 calls.
3111
Collin Winter62903052007-05-18 23:11:24 +00003112- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113 "except E as target:". This is to provide forwards compatibility
3114 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003115
Brett Cannon229cee22007-05-05 01:34:02 +00003116- Deprecate BaseException.message as per PEP 352.
3117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003119 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003120
Vinay Sajip8549ce32007-05-06 17:53:37 +00003121- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003122 setting a plain string, ie don't expand to single letter identifiers.
3123
Raymond Hettinger13936692007-04-11 18:40:58 +00003124- Request #1191699: Slices can now be pickled.
3125
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003126- Request #1193128: str.translate() now allows a None argument for
3127 translations that only remove characters without re-mapping the
3128 remaining characters.
3129
Georg Brandl5cb76c12007-03-21 09:00:39 +00003130- Patch #1682205: a TypeError while unpacking an iterable is no longer
3131 masked by a generic one with the message "unpack non-sequence".
3132
Neal Norwitzaa754b72007-03-21 06:39:48 +00003133- Remove unused file Python/fmod.c.
3134
Guido van Rossum143b5642007-03-23 04:58:42 +00003135- Bug #1683368: The object.__init__() and object.__new__() methods are
3136 now stricter in rejecting excess arguments. The only time when
3137 either allows excess arguments is when it is not overridden and the
3138 other one is. For backwards compatibility, when both are
3139 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003140 warning later). Also, type.__init__() insists on the same signature
3141 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3144 object to complex using its __complex__() method before falling back
3145 to the __float__() method. Therefore, the functions in the cmath
3146 module now can operate on objects that define a __complex__()
3147 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Patch #1623563: allow __class__ assignment for classes with
3150 __slots__. The old and the new class are still required to have the
3151 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Patch #1462488: Python no longer segfaults when
3157 ``object.__reduce_ex__()`` is called with an object that is faking
3158 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003163- Patch #1444529: the builtin compile() now accepts keyword arguments.
3164
Georg Brandl7b9c5552007-03-12 14:30:05 +00003165- Bug #1678647: write a newline after printing an exception in any
3166 case, even when converting the value to a string failed.
3167
Georg Brandl871f1bc2007-03-12 13:17:36 +00003168- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169 its argument, if it exists. If not, it will work like before. This
3170 allows customizing the output of dir() in the presence of a
3171 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003172
Collin Winter276887b2007-03-12 16:11:39 +00003173- Patch #922167: Python no longer segfaults when faced with infinitely
3174 self-recursive reload() calls (as reported by bug #742342).
3175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Patch #1491866: change the complex() constructor to allow
3180 parthensized forms. This means complex(repr(x)) now works instead of
3181 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003182
Georg Brandlaa2321b2007-03-07 00:40:28 +00003183- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003184 makes the filenames the warning module prints much more sensible
3185 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003186
Georg Brandl49aafc92007-03-07 00:34:46 +00003187- Variant of patch #697613: don't exit the interpreter on a SystemExit
3188 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189 variable is given, but break into the interactive interpreter just
3190 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Bug #1674503: close the file opened by execfile() in an error
3196 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003197

3687 log file rotation using e.g. newsyslog or logrotate. This handler is
3688 only useful in Unix/Linux environments.
3689
Georg Brandlfb4b3b72007-04-24 15:27:13 +00003690- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3691 (as opposed to the command line) will now write file names ending in
3692 ".cpp" too.
3693
Facundo Batistad918a652007-04-24 13:54:38 +00003694- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695 the client's request was successfully received, understood, and
3696 accepted. Now in these cases no error is raised in urllib (issue
3697 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003698
Georg Brandl3ee81df2008-05-17 18:14:43 +00003699- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003705- Added a timeout parameter to the constructor of other protocols
3706 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3707 work started with create_connection() and timeout in httplib, and
3708 closes patch #723312.
3709
Vinay Sajip8549ce32007-05-06 17:53:37 +00003710- Patch #1676823: Added create_connection() to socket.py, which may be
3711 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003712 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003713
Martin v. Löwis0af33882007-03-23 13:27:15 +00003714- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3722 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003723 directories.
3724
Georg Brandl8f06d022007-03-16 07:55:09 +00003725- Bug #1681228: the webbrowser module now correctly uses the default
3726 GNOME or KDE browser, depending on whether there is a session of one
3727 of those present. Also, it tries the Windows default browser before
3728 trying Mozilla variants.

3733 initialization failed.
3734
Georg Brandlf66b6032007-03-14 08:27:52 +00003735- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736 AttributeError instead of an IOError when the server's response
3737 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Patch #957650: "%var%" environment variable references are now
3740 properly expanded in ntpath.expandvars(), also "~user" home
3741 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003742
Georg Brandl3ee81df2008-05-17 18:14:43 +00003743- Patch #1429539: pdb now correctly initializes the __main__ module
3744 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003745 correctly now.
3746
Georg Brandlbad6f192007-03-13 21:32:56 +00003747- The nonobvious commands.getstatus() function is now deprecated.

3753
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754- Patch #1530482: add pydoc.render_doc() which returns the
3755 documentation for a thing instead of paging it to stdout, which
3756 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003757
Georg Brandl3ee81df2008-05-17 18:14:43 +00003758- Patch #1533909: the timeit module now accepts callables in addition

Georg Brandld9bef352007-03-13 19:32:21 +00003762
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete"
3764 parameter which can be set to False to prevent the default
3765 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003766
Georg Brandl9e6b4702007-03-13 18:15:41 +00003767- Patch #1581073: add a flag to textwrap that prevents the dropping of
3768 whitespace while wrapping.
3769
Georg Brandl92a6bae2007-03-13 17:43:32 +00003770- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771 are set for invalid interpolation sequences that would lead to
3772 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003773

Collin Winter22c42ba2007-03-10 02:51:26 +00003807

3815 returned string up to the first NUL character.
3816

3826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- unittest now verifies more of its assumptions. In particular,
3828 TestCase and TestSuite subclasses (not instances) are no longer
3829 accepted in TestSuite.addTest(). This should cause no
3830 incompatibility since it never made sense with ordinary subclasses
3831 -- the failure just occurred later, with a more cumbersome
3832 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003833

3841 given a unicode argument and os.listdir() returns unicode filenames.
3842
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843- Patch #1673619: setup.py identifies extension modules it doesn't
3844 know how to build and those it knows how to build but that fail to
3845 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004220- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221 time so that opening a database previously created with the DB_DUP
4222 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4223 opens. Specifically: dictionary assignment to a DB object will
4224 replace all values for a given key when the database allows
4225 duplicate values. DB users should use DB.put(k, v) when they want
4226 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004227

4233 characters with ASCII value less than 32. Also, it correctly quotes
4234 dots only if they occur on a single line, as opposed to the previous
4235 behavior of quoting dots if they are the second character of any
4236 line.
